The waves are reflected by internal discontinuities or external boundaries. A displacement transducer located close to the impact point measures the time history of the

Annika Schmidt,Karin Wolf-Ostermannc insitu-tests and dynamic calculations. The basic idea is to detect damages of bridges via changes of the dynamic parameters. The steps of application are dynamic insitu-testing, mathematical modelling, fitting of the mathematical model to the test results and sensitivity investigations. The develo
